摘    要:对兰科(Orchidaceae)石豆兰属(Bulbophyllum)二新种,副萼石豆兰(B.malipoense Z.J.Liu,L.J.Chen&W.H.Rao)和小副萼石豆兰(B.minor Z.J.Liu,L.J.Chen&W.H.Rao)作了描述和绘图。该二新种属于石豆兰属副萼组(Bulbophyllumsection BisetaJ.J.Verm.ex N.Pearce,P.J.Cribb&J.Renz),与该组的刺萼石豆兰(B.bisetum Lindl.)相似,区别在于两新种的叶片先端二裂和唇瓣无毛。小副萼石豆兰与副萼石豆兰的区别在于假鳞茎椭圆球形;叶片卵状椭圆形,长1.2~2 cm;侧副萼片较短,长约1 mm;中副萼片几乎与两侧萼片边缘合生。

关 键 词:石豆兰属副萼组(Bulbophyllum  section  Biseta)  副萼石豆兰(B.malipoense)  小副萼石豆兰(B.minor)  新种  兰科(Orchidaceae)

Abstract:Bulbophyllum malipoense Z.J.Liu,L.J.Chen & W.H.Rao and Bulbophyllum minor Z.J.Liu,L.J.Chen & W.H.Rao,two new orchid species from China,are described and illustrated.Both of them belong to Bulbophyllum section Biseta,and are akin to B.bisetum.Bulbophyllum malipoense differs from B.bisetum by having bilobed-tipped leaves and a glabrous lip,and B.minor differs from B.malipoense by having ellipsoid-globose pseudobulbs,ovate-elliptic leaves 1.2-2 cm long,shorter lateral calycules ca.1 mm long,and a central calycule almost entirely adnate to the connate margins of the lateral sepals.
Keywords:Bulbophyllum section Biseta  B.malipoense  B.minor  New species  Orchidaceae
